METHOD OF COOLING AND DRAWING FLUIDS FROM CASKS, 850.

Specification of Letters Patent No. 15,177, dated June 24, 1856.

T0 all whom t may concern:

Be it known that I, F. EsPENsoHADE, of lVilliamsport, in the county of Lycoming and State of Pennsylvania, have invented a new and improved cooling device to be attached or applied to barrels, casks, and other vessels for the purpose of allowing liquids to be drawn direct therefrom in a cool state; and I do hereby declare that t-he following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, said drawing being a longitudinal vertical section of a barrel with my improvement applied to it, the improvement being also bisected vertically through its center.

My invention consists in having a cooler peculiarly constructed provided with a pump and connected with the barrel as will be hereinafter fully shown and described so that liquids may be drawn from the barrel in a cool state without admitting air into the barrel.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, represents a cask or barrel properly supported by a frame or rack B, and C, represents a vessel of cylindrical or other proper form supported by a frame D. The vessel C, has an annular chamber E fitted within it, a space (a) being allowed between the outer sides of the chamber E, and the inner side of the vessel C, and a space (b) being allowed at the center or between the inner sides of the chamber E. These spaces (a), (L) communicate with the body of the vessel C, as plainly shown in the drawing.

F, is a faucet which communicates with the chamber E, said faucet passing through the side of the vessel C.

G is a pipe or tube which passes from the vessel C, to a faucet I-I, which passes into the barrel A.

Underneath the vessel C, there is placed a cylinder I having a piston head J within it.

K is the piston rod which passes through the back end of the cylinder I, and is connected to an arm (c) the lower end of which is attached to a treadle L, which is pivoted to the frame D.

M, is a spiral spring one end of which is attached to the back end of the cylinder I, and the opposite end to the piston head J. The spring M, keeps the piston head at the back end of the cylinder I.

N, is a valve which is placed between the cylinder I and the vessel C, the valve being near the front end of the cylinder. O, is a faucet which is placed in the front end of the cylinder I.

The chamber E is filled with ice. The waste water may be drawn from the chamber by means of the faucet F. The faucet H being open, the liquid in the barrel A will passdown the pipe G and ill the vessel C, the liquid in said vessel being kept cool by the ice in the chamber E. The liquid in the vessel C is drawn therefrom when desired by opening the faucet O and depressing the outer end of the treadle L, the piston head J, forcing the liquid through the faucet O, and at the same time closing the valve N. The vessel C, may be placed at any convenient distance from the barrel A.

The above invention is extremely simple and valuable especially when malt liquids are kept on draft, as the liquids may be drawn in a cool state directfrom the vessel C, without allowing air to pass into the barrel A.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,

The vessel C, provided with an ice chamber E, and having a pump connected with it and the vessel communicating with the barrel A, by means of the pipe G, the above parts being arranged substantially as shown for the purpose specified.
